The Nightlight Falls Prevention Study
A Pragmatic Crossover Trial to Test the Effectiveness of a Novel Lighting System to Reduce Nighttime Falls in Persons With Alzheimer's Disease and Related Dementias
Source: ClinicalTrials.gov · Last updated 21 Apr 2026
Brief summary (registry, in English)
This project will test the effectiveness of a novel intervention consisting of unobtrusive, low-intensity, horizontal and vertical lights that outline the bathroom or entry way doorframe in residents' rooms and provide visual cues to promote postural stability. Specifically, this pragmatic crossover trial will enroll 335 assisted living residents with dementia and follow them for one year, comparing the incidence of nighttime falls during the lighting condition to the incidence of falls during the control condition; secondarily, it will determine whether and to what extent the intervention effect is modified by resident- and environmental-level risk factors, and satisfaction with the lighting system.
